This study was conducted to investigate the effect of an uncooked powdered food(UPF) on the weight loss and changes of the biochemical nutritional status for 20 overweight and 26 obese women in Iksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Also anthropometric and biochemical measurements before and after the UPF program were estimated. The intake of energy, lipid and protein decreased and the quality of meals improved as people started to take UPF. Due to the energy loss by taking UPF, weight and body fat decreased significantly. The percentage of the body fat was high among the weight lost, from which we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening the body fat. The most positive change among biochemical changes by taking UPF was the decrease of serum lipid contents. When overweight and obesity women replaced two out of three meals with UPF for 3 month period, no significant nutritional problems occurred. It seems that the 12weeks of UPF program used in this study was effective in improving anthropometric indices without producing the deficiency of iron or other susceptible nutrients.

The objective on this study was to investigate effect of KH, which was composed of 9 kinds of oriental herbs tonifing the blood, against toxicity of 5-flurouracil(FU) through animal study. Reduction of WBC and platelet after treating S-FU was significantly recovered by KH. KH also rehabilitated immune gene expression of interleukin-2(IL2) and $Interferon-{\gamma}\;(IFN-{\gamma})$ by RT-PCR. In addition, in situ hybridization of spleen showed that KH treatment increased mRNA expression of IL2. In addition to the immune action, antitumor activity on 5-FU was not affected by KH treatment. In conclusion, our study demonstrated that KH alleviated damage of hematopoiesis system induced by f-FU without toss of antitumor activity.

Nomura Kohsan Corp. is producing oxides, such as ZnMn$_2$O$_4$, ZnFe$_2$O$_4$, and ZnO, by burning the used dry manganese cells and by sorting out the remnant materials. It is possible to use the recycled materials of the spent dry batteries as the raw materials of deflection yoke cores. Making hish roasting temperature in the recycling system has an effect in reduction of the impurities. As a result, the loss of the cores using the recycled materials is lower. When using the recycled materials, it is required to add Mg (OH)$_2$. ZnO, and Fe$_2$O$_3$in order to rectify the composition of the MnMgZn ferrite for deflection yoke core applications. Furthermore, in order to disappear ZnMn$_2$O$_4$in the formation, it is necessary to control at higher calcining temperatures. The MnMgZn ferrite of using the recycled materials becomes Toss equivalent to the conventional material. TDK Corp. is manufacturing the deflection yoke cores from 1996 using the material recycled from the spent dry batteries.

In this study, Two types of polyester fabrics were hydrolysed with NaOH using the CDR m/c of pad-steam type and the Sofleena m/c of liquor-flow type to determine the alkali hydrolysis properties of polyester fabrics. The results were as follows: Under the same conditions, the weight loss of charmeuse was about 0.5% and 2~3% higher than that of pebble with CDR m/c and with Sofleena m/c, respectively. The weft density of pebble decreased about 14picks/inch with CDR m/c and 3picks/inch with Sofleena m/c comparing to the untreated sample at 18% of weight loss, while the weft density of charmeuse decreased about 5picks/inch with CDR m/c and 2picks/inch with Sofleena m/c at 20% of weight toss. K/S value decreased almost identically within about 11% weight loss of pebble and 8% of charmeuse processed with both CDR and Sofleena. However, in the above these weight losses, K/S value of the fabrics processed with Sofleena was higher than that of fabrics processed with CDR. The bending rigidity of warp direction of the fabrics ($2{\times}10^{-2}gf.cm^2 /cm$ higher for charmeuse and ($7{\times}10^{-3}gf.cm^2 /cm$ higher for pebble) processed with CDR m/c was higher than that of the fabrics processed with Sofleena m/c.

축류형 터빈이 부분분사에 의하여 작동하는 경우에 성능을 예측하는 모델을 개발하였다. 부분분사에 의하여 작동하는 터빈에서 발생되어지는 손실을 windage 손실, 확산손실, 혼합손실로 분류하여 각각의 모델을 적용하여 효율을 예측하였으며 실험의 결과와 비교하였다. 타 모델과는 달리 세 가지의 손실을 모두 고려한 본 연구의 결과가 실험결과와 잘 일치하고 있음을 보였으며 부분 분사량을 변경한 경우에도 실험결과와 일치된 결과를 보였다. 본 연구의 예측모델은 부분분사 터빈의 성능을 예측하는데 적용 되어질 뿐만 아니라 높은 예측정확도를 보였다.

한 조로 사용 되는 네 개의 윷가지의 크기와 모양이 같아서 각 윷가지의 등이 나올 확률이 같은 윷놀이를 생각한다. 윷놀이에서는 모나 윷이 나오면 한 번 더 던지는 규칙이 있으므로, 한 사람의 차례에서 윷을 던져 말이 가는 거리 X에 관심이 있게 된다. 따라서, 거리 X에 대한 확률질량함수를 구하고, 각 윷가락의 등이 나올 확률의 몇 개의 값에 대하여 확률을 표로 나타낸다. 또한, 거리 X의 기댓값, 분산, 왜도, 첨도를 구하며, 주어진 윷의 등의 확률의 몇 개 값에 대하여 값을 구하여 표로 나타낸다.

This research aims to develop textile patterns using mythical motives based on Buldoje in the Jeju myth. this textile design is not only decoration effect by filling the space, but also plays the original role of a pattern by expressing its symbolic meaning. The research methods are as follows: 1) Using integral analysis on materials related to the myth of Jeju and Gime used in Buldoje Gut, where Halmangbonpuli story is performed to set formative elements for textile design and their meanings; 2) Designing motive by composing formative elements; 3) Coloring properly; and 4) Layout motives. Adobe CS5 (Photoshop, Illustrator) and TexPro, a design CAD program, were used for textile design. Motives were combined in a various ways. Two-directional, four-directional, set, rotating, toss layout techniques, which are frequently used in apparel design and able to reduce cloth use, were used in developing patterns. Coloring methods including tone-in-tone and Faux camaieu were used to deliver coherence and soft effects. Developed textile design symbolizes the desire for the conception of a child, birth, and health, so it is made on baby clothes. In doing so, the plan for development of a fashion-cultural product applying Jeju myth symbol is suggested.

Customized services to a sleep induction for better sleepcare are more effective because of different satisfaction levels to users. The EOG data measured at the frontal lobe when a person blinks his eyes can be used as biometric data because it has different values for each person. The accuracy of measurement is degraded by a noise source, such as toss and turn. Therefore, it is necessary to analyze the noisy data and remove them from normal EOG by filtering. There are low-pass filtering and high-pass filtering as filtering using a frequency band. However, since filtering within a frequency band range is also required for more effective performance, we propose a machine learning model for the filtering of EOG data in this paper as the second filtering method. In addition, optimal values of parameters such as the depth of the hidden layer, the number of nodes of the hidden layer, the activation function, and the dropout were found through experiments, to improve the performance of the machine learning filtering model, and the filtering performance of 95.7% was obtained. Eventually, it is expected that it can be used for effective user identification services by using filtering model for EOG data.

거대해지고 복잡해진 건설프로젝트에서 건설 생애주기 동안 필요한 모든 정보를 효과적으로 관리하기 위한 BIM에 대한 관심이 증가하고 있다. BIM을 이용한 협업에서 정보의 교환과 공유는 이윤을 극대화할 수 있는 중요한 요소이다. IAI에서는 건설프로젝트의 모든 참여자가 사용할 수 있는 표준 파일포맷으로 STEP기반의 IFC모델을 제시하고 있고 현재 $2{\times}3$버젼이 게시되어 있어서 이를 지원하는 BIM소프트웨어에서 IFC포맷으로 내보내거나 들여올 수 있다. 하지만 실험결과 IAI로부터 IFC호환성 인증을 받은 BIM소프트웨어들이라도 IFC포맷의 파일을 내보내거나 들여올 때 정보가 손실되거나 변형되는 오류가 발생하였다. BIM소프트웨어 사용자들은 정보공유를 위해 IFC파일을 사용했을 때 자신도 모르게 에러가 발생해서 프로젝트에 큰 손실을 입을 수도 있다. 본 연구에서는 호환성 검사에 대한 기존의 연구를 살펴본 후 IAI의 검사 과정을 조사하고 문제점을 도출한 후 문제점에 대한 해결방안을 제시하고자 한다.
